Description

The portable and collapsible workbench

Technical field

The utility model belongs to building, decorates household work platform structure technical field.

Background technology

Existing building, decorate, the workbench that household is used, promptly can carry out the bracing frame of operation in high position more by workbench for construction or user of service, normally adopt ladder or stool, but this dual mode all has weak point, though ladder can make height of table satisfy construction requirement, the loose shakiness but its structure seems, center of gravity is easily moved with the personnel on the workbench and is changed, very easily cause rocking and tumble injury of workmen on the platform, and ladder certainly will increase foot rest length in order to satisfy the height needs, make the ladder structure large and long heaviness that seems, very inconveniently carry and place.Stool structurally its foot rest adopts the mode of fixedlying connected with workbench, and is not only wide in shape, not only long but also high, more is unfavorable for carrying and placing, and construction site and environment that this structure only is suitable for fixing usually use.

Summary of the invention

The purpose of this utility model provides a kind of building that is suitable for flowing, decoration construction personnel just and uses at home in order to overcome above-mentioned the deficiencies in the prior art part the both stable portable and collapsible workbench that can keep height of table, appearance and size compactness of structure.

The purpose of this utility model is achieved by the following technical solution.

This portable and collapsible workbench, bipod and workbench that it is symmetrical are hinge engaging structure, between foot rest and workbench, be respectively arranged with bracing or strutting arrangement, this bracing or strutting arrangement includes sleeve, support bar and nut, put at support bar on the fragment position of sleeve and offer screw thread, bracing or strutting arrangement two ends and workbench and foot rest are hinge engaging structure also, and any hinge position is set to exceed another hinge one segment distance in the foot rest.

In the sleeve of bracing or strutting arrangement, be provided with a limit spring; The sleeve of bracing or strutting arrangement and post position can exchange; The position that bracing or strutting arrangement and foot rest are hinged is to be positioned on the cross bar in foot rest stage casing; In the pin pipe that constitutes foot rest, be provided with extension rod, on this extension rod is vertical, offer fixing hole, by the screwed pipe of on the pin pipe, offering, the position of adopting its pin pipe of bolting to prolong; The hinge axle center of bracing or strutting arrangement is lower than foot rest hinge axle center respectively on horizontal level, so that foot rest forms a leaning angle α through the sleeve of folding rear support device and the plane of workbench, α is 5 °～20 °.

When the utility model is in user mode, bipod launches, because hinge is provided with the low pin pipe in position and than hinge position short one section of high pin pipe is set, and workbench is horizontal, at this moment, bracing or strutting arrangement is an extended configuration, support bar is pulled out from sleeve, and the thread segment that exposes screws by nut and props up sleeve, makes sleeve and support bar be a rigid structure, support foot rest, make that foot rest is unlikely to shake and rotate.Workbench raises if desired, with isometric the pulling out of extension rod in each pin pipe, screws in the screw of pin pipe and puts in the fixing hole of extension rod by bolt, extension rod is fixed, thereby increased the length of foot rest.When not using the utility model its folding being got up, the turn nut makes support bar loosening, by inside rotation foot rest support bar is extend in the sleeve, thus make the foot rest folded flat by and workbench.Because it is different that the foot rest hinge position at two ends is provided with height, the foot rest that hinge position is high is folded near workbench earlier, and then the low foot rest in folding hinge position, makes parallel the reclining of bipod energy, and compact conformation seems.At this moment, because the hinge axle center of bracing or strutting arrangement is lower than foot rest hinge axle center respectively on horizontal level, make foot rest form a leaning angle α through the sleeve of folding rear support device and the plane of workbench, when the limit spring in the sleeve is subjected to the compression of support bar, present a reaction force, and the leaning angle that forms between sleeve and the workbench can make bipod by this angle self-locking just, unlikely rotating and stretch and open.

Further set forth the utility model below in conjunction with Figure of description.

Fig. 2 is the side view of the utility model deployed condition;

Fig. 3 is the folding schematic diagram of the utility model.

The specific embodiment

The utility model can adopt various materials to make, for example timber, plastics, alloy etc.Present embodiment selects for use the steel plate of 6 millimeters thick to make workbench 1, makes a lid shape structure by shearing, flanging, is welded with gusset 17 in the middle of the workbench bottom surface.Foot rest 2,3 is formed through assembly welding by metal pipe material 12, cross tube 11, sheer pole 10, the connected mode of cross tube and workbench is: becket 18 is enclosed within cross tube 11 two ends respectively, again cross tube is embedded the flanging inboard of workbench, then becket 18 is fixedly welded on the flanging inboard of workbench 1, has so just formed hinge arrangement.Sleeve 5 one ends of bracing or strutting arrangement 4 and the gusset 17 on the workbench 1 are hinged; The sheer pole 10 of support bar 6 one ends and foot rest is hinged, in sleeve 5, be provided with a limit spring 8, stable in order to guarantee the foot rest after folding, the

hinge axle center

20,21 of bracing or strutting arrangement 4 is lower than foot rest 2

hinge axle center

22,23 respectively on horizontal level, so that foot rest 2 forms a leaning angle α through the sleeve 5 of folding rear support device and the plane of workbench, α can choose arbitrarily between 5 °～20 °.After foot rest was folding, sleeve and workbench maintained a leaning angle α, thereby formed self-locking state.Attacked screw thread 9 on one section in support bar 6 stretches into sleeve 5, and one dish-shaped nut 7 has been arranged at the thread segment rotation set.In the pin pipe 12 of foot rest, be with the metal tube extension rod 13 of reduced size respectively, longitudinally offer fixing hole 14 at extension rod 13, by set bolt 16 and the screw 15 on pin pipe 12, offered extension rod 13 is stretched out piecemeal along pin pipe 12, thereby increase the length of foot rest, workbench 1 is raise.Also can adjust bipod pipe extension rod and stretch out different length, workbench steadily is placed on the rugged stair.When not using the utility model at ordinary times, can be with the folding respectively workbench 1 of being close to of foot rest 2,3, because foot rest 2 hinges are provided with near workbench 1, the hinge of foot rest 3 will hang down a pin pipe 12 cross section nominal diameter positions, when foot rest 2 foldings after be close to workbench 1, foot rest 3 steadily Horizon leans against on the foot rest 2.When foot rest 2 was in deployed condition, in order to keep Stability Analysis of Structures and avoid rocking, the flanging place of being close to workbench 1 at pin pipe 12 was provided with fixed block 24.Because the hinge of foot rest 3 is lower than foot rest 2 positions, therefore, the pin pipe of foot rest 3 is lacked one section than the pin pipe of foot rest 2, to guarantee the horizontal positioned of workbench.Carry for convenience, be welded with a metal handle 19, the utility model after folding can be resembled carrying the suitcase to be carried into Anywhere in flanging one outside of workbench 1.
